Did you see the ending where the now supposedly evil Voodoo Lady has LeChuck's remains, has bargained with Morgan LeFlay and pretty much straight-out says there's a big event coming? I don't really know how that can be interpreted as something other than an open ending.

Agree! We still don't know anything about the real Voodoo Lady's plans and what does it has to do with LeChuck, Guybrush, the Guybrush's Hand and Morgan LeFlay.

Damn! It was one of the most important revolution in the MI story and we don't know anything about it, because Episodes 4 and 5 barely began to introduce it! And the only reason for opening such an important plotline without closing it is because it was meant to be continued in a SEQUEL!!!

Yeah.

I can live without knowing what happened there. It's an open ending but it doesn't leave the game that happened before unsatisfying. That's still resolved. The post game ending is like a hint for FUTURE events possibly, not undermining current ones.

A hint for future events, starting from important events that we see in this game. So, we have a "main" plotline that's ended and closed (the Pox story), and a "secondary", but much more important plotline, because involves all the Monkey Island saga, (the Voodoo Lady's Plans) that is totally open. If you think that Tales is only the Pox and the Esponja stories you're totally wrong...because the Pox and the Esponja stories are obviously told as little elements of a much bigger story that has not been told yet.
